Kinda sucks here ngl, but Europe is SO small. Like that high school graduate who came back from gap year to a high school party saying he traveled “all over Europe” just to pick up girls. Come on guy, it’s like a metro rail pass and a two weeks time.

Yeah, it sucks in the US but we only have to deal with OUR idiots, we don’t have to deal with our own idiots PLUS a neighbor’s that are crazy unstable. I’m not in missile range of anything since the 60’s. Just saying.

OK… 2 seconds on Google: United States: 9.8 million square kilometers. Europe: 10.2 million square kilometers.

Do you also need me to search for kilometer?

Yes but he has a point : you can’t travel in the USA by train, it’s a fucking nightmare. Whereas in EU it’s quite easy and cheap.
Nobody does Lisbon-Tallinn by train either. It would be almost impossible or very expensive.
Interrail?
Europe 44 different countries. USA 1 country.
There is alsorts wrong here. 1, you referred to Europe as one single land mass, not individual countries. 2, you USAians can never make up your minds whether you’re some massively varied culture or not.
